There are two exoplanets in the solar system which are similar to Earth, at least when it comes to climate, the researcher says Kepler-165 is the first known planet earth-shaped planet. This means that it is a fair distance from the pool to the pool on the surface for its liquid star.
The study, which appeared in the celestial journal, used simulations to analyze and identify the spin axis dynamics of Exoplanet.
Those dynamics determine how much a planet bends on its axis and how the tilt angle develops over time. The axial tilt contributes to the weather and the climate because it is affected by how the sunlight comes to the surface of the planet.
According to Researcher, the axial tilt of Kepler-16 F is constant, like the Earth, it is believed that it has fixed monsoon and stable environment. It is also possible that Kepler-62F, an Earth like planet that revolves around a star of 1,200 light-years away from us.
How important is the axial tilt for the climate? Researchers say that large variability in axial tilt may be one of the main reasons why Mars changed billions of years ago from the water situation in today’s barren desert.
Gongjie Lee, assistant professor of physics at the Georgia Institute of Technology, says, “Mars is in a living area in our solar system, but its axial tilt is very unstable-varies from zero to 60 degrees”, who study with graduation Student Yutong Shan from Harvard-Smithsonian Center for Astrophysics led
“That instability probably contributed to the destruction of the Martin Atmosphere and the evaporation of surface water.”
The orientation angle of a planet’s orbit around its host star can be generated through gravitational interaction with other planets in the same system. If the orbit of the spin axis (similar to the circular motion shown by the rotating axis of the top or gyroscope) was to move the orbit at the same speed, then the spin axis would sometimes rotate dramatically.
Mars and Earth interact with each other simultaneously with Mercury and Venus. Consequently, by themselves, their spin axis occurs before the rate of orbital circulation, which can cause great variation in their axial tilt.
What about the moon?
Fortunately, the Moon keeps the Earth’s diversity in check. The Moon enhances the exact rate of spin axis of our planet and separates it from the orbital emission rate. On the other hand, there is not enough satellite to stabilize the axial tilt of Mars.
“It seems that both exoplanets are very different from Mars and Earth because they have a weak relation with their own planets,” says Lee
Kepler-16 F is less than 10 percent in the radius compared to the Earth, but its mass, structure, and density remains a mystery. It is in the class of its host starring every 130 days.
According to NASA, when standing at 186 F, that brightness of that star will be bright in the afternoon, before sunset on the earth will appear as bright as the sun.
Kepler-16 F is located in the constellation Cygnus as part of the Five Planet Star System.
Kepler-62F was the most exoplanet like Earth until scientists saw 186 F in 2014. Kepler-62F is 40 percent larger than Earth and is probably a terrestrial or ocean-covered world.
It is not to say that Exoplanet has water, give life alone. But both are relatively good candidates.
Shan says, “I do not think we consider enough about the origin of life to cancel the possibility of their presence on the erratic weather planets.” Even on Earth, life is remarkably various and incredible flexibility has been shown in an extraordinarily hostile environment.
But a climactic static planet could be a more comfortable place to start.
